Marine electric generator flushing system

Abstract

A marine electric generator flushing system for a boat has a liquid container attached in the generator raw cooling water intake line and mounted in a boat hull positioned along the water line of the boat. The liquid container has a fresh water inlet that allows a fresh water hose to be connected thereto and which automatically blocks the raw water line anytime fresh water is entering the liquid container so that fresh water is drawn through the generator cooling system.

1. A marine electric generator flushing system for a boat comprising:
 a liquid container mounted in a boat hull having a water cooled marine electric generator therein; a container inlet having an inlet conduit connected thereto from an exterior of said boat hull for the passage of raw water therethrough into said liquid container; 
 a container outlet having an outlet conduit connected thereto for coupling said liquid container outlet to said marine electric generator for passing cooling water from said liquid container to said electric generator; 
 an exhaust conduit connected between said marine electric generator and the exterior of said boat for the passage of cooling water from said electric generator to the exterior of said boat; 
 a fresh water inlet connected into said liquid container for feeding fresh water into said liquid container when a fresh water source is connected thereto; 
 a float valve located in said liquid container and operatively connected to said fresh water inlet to control the flow of fresh water into said liquid container responsive to a level of water in said container; and 
 a container inlet valve located in said liquid container for closing said container inlet, said container inlet valve being connected to said fresh water inlet valve for activating said container inlet valve responsive to water pressure from said fresh water inlet when fresh water is applied to said fresh water inlet; 
 whereby said liquid container has raw cooling water from said container inlet cut off when fresh water under pressure is applied to said fresh water inlet as fresh water is entering said liquid container to allow said marine electric generator to be flushed with fresh water from said liquid container while blocking the entrance of raw cooling water entering said liquid container. 
 
     
     
       2. The marine electric generator flushing system for a boat in accordance with  claim 1  in which said container inlet valve has a water pressure activated piston therein for driving a valve element against a valve seat thereby blocking the entry of raw cooling water into said container. 
     
     
       3. The marine electric generator flushing system for a boat in accordance with  claim 2  in which said container inlet valve piston is spring loaded to hold said valve element in a container inlet open position until water pressure is applied to said container inlet valve piston. 
     
     
       4. The marine electric generator flushing system for a boat in accordance with  claim 3  in which said float valve closes off said fresh water inlet upon said liquid container having a predetermined level of liquid thereon. 
     
     
       5. The marine electric generator flushing system for a boat in accordance with  claim 4  in which said float valve has a float that rises and falls with the water level in said liquid container. 
     
     
       6. The marine electric generator flushing system for a boat in accordance with  claim 5  in which said container inlet valve has a manually operated valve which can be closed when winterizing said marine electric generator cooling system. 
     
     
       7. The marine electric generator flushing system for a boat in accordance with  claim 6  in which said liquid conduit inlet has the container inlet valve's valve seat formed therein. 
     
     
       8. The marine electric generator flushing system for a boat in accordance with  claim 7  in which said container inlet valve is connected to said fresh water inlet by a conduit therebetween.
